The yellow-headed wood warbler ( Setophaga pensylvanica , syn .: Dendroica pensylvanica ) is a small insectivorous bird from the genus of the wood warbler ( Setophaga ) in the family of the wood warbler (Parulidae).
features
It got its name because of the yellow to greenish crown on the head, which in the adult male can overflow into orange. The female is similar to the male, but the plumage is generally more blunt. On the flanks of the white underside plumage there are mostly extensive rust-colored stripes, which are not as pronounced in the female as in the male. There are yellow spots on the gray-black to brown-black wing covers. The back plumage is gray-black with white stripes. The thin, pointed beak and legs are black. The yellow-headed wood warbler has white plumage on the face with black stripes over the eyes that can run down to the neck. In the young birds, the crown, neck and back are green and the face is gray. Even with them, the rust-colored side stripes are hardly pronounced.
nutrition
The food of the yellow-crowned wood warbler consists mainly of insects , only occasionally fruits are eaten.
Reproduction
The nest, made of parts of plants and hair, is built in a small tree or bush close to the ground. The female lays three to five white eggs covered with brown spots in the nest, which are hatched in a period of 12 to 13 days. The chicks fledge after ten to twelve days. The brown-headed cowbird ( Molothrus ater ) lays its eggs in the nest as a brood parasite like the lemon warbler ( Protonotaria citrea ) and the yellow-headed warbler.
Occurrence and threat
The breeding areas are in the east of North America , from southern Canada to the south to Georgia via New England , the Great Lakes and the Appalachians . In winter the yellow-headed wood warbler moves to central Mexico and central South America. In the south-eastern areas, stocks have decreased. It is assumed that habitat destruction is the main cause. In the northern areas of distribution, the populations are still reasonably stable or local populations have declined.
